TABULATQJR FOR TYPE-WRITERS.

To all ujhom may concern v Be It known that I,- '1lm1onon EUGEN BUSCHMANN, a subject of the Emperor of I Germany, residing at Chemmtz, Gerinany have invented certain new and useful Improvements in Tabulators for Type-lVriters, Of which the following is a specification.

. This invention relates to tabulators for typewriters and is an improvement in or modification of the tabulator mechanism described in the specification of my prior Patent No. 1035778, granted August 13, 1912, having for its object a simplification in the adjustment of-the tabulator stop bars with relation to the carrying bars for the tabulator stops which correspond to the differ ent headings for invoices required for use. The simplification or improvement in the adjustment consists therein that the adjusting apparatus is so formed that the changing from one position of the. tabulator stop bars to another position is performed by turning the parts effecting the adjustment, to the right or to the left.

The invention is shown by way of example in the accompanying drawings, in which:-

Figure l is a lateral sectional elevation of the frame of the typewriter, and showing the tabulator device constructed according to this invention; Figs. 1* and 1 are details. Fig. 2 is a plan according to Fig. 1.

- Figs. 2 to 2 show the adjusting apparatus for the stop bars in diiferentworking posi' tions. Fig. 3 is a back elevation. Fig. 3 'is a plan on the guiding member for the stop bar casing. Fig. 4 is a partial elevation corresponding to Fig. 1, but seen from the other side. it

The paper carriage l. as described in the specification of the prior patent, above mentioned is guided in the known manneron the front and back carriage bar. and carries atthe back thereof the supporting or"tabulator bars 2 which are preferably arranged beside ea'ch other, for the tahulator stops 3. Stop bars 4 cooperate with these stops The stop bars 4 are inclosed and guided in a casing 6, and are lifted by the talmlatorkcy lever 5 against the action of their tension springs 8, for engagement with the stops 3. All this is substantially described in the specification before referred to.

For the purpose of adjusting the stop Specificatioh of Letters Batent. Patented Sept. 22, 1914. Application filed November 22, 1913. SerialNo. 802.575.

bars 1 relatively'to the different carrying bars 2 for the tabulator stops corresponding to the different headings of invoices required, the stop bar casing 6 is connected by means of a link 9 with the pin of a crank disk 10 situated on a shaft 10.

The shaft 10 is mounted in a bearing member 12 secured on the frame of the typewriter and carries at its other end a bevel wheel 11*, which is in gear with a second bevel wheel 11 mounted on the shaft 14.

The shaft 14 carries at the front of the typewriter, a knob 15 and pointer 16 adapted to move over an indicator scale 17. The crank disk 10 is provided with notches on its circumference with which a clamping ball 13 can engage. The clamping ball 13 is arranged in a holding apparatus on the bearin member 12, and is situated under the in uence of a spring, which has a constant tendency to cause the clamping ball go IEngage with the notches in the crank The stop bars 4 together with theircasing 6, pivot about an axis 7 securely mounted- 'a fulcrum pin 25 and are adapted to be operated against the action of tension springs their front ends being guided in the slots of a comb-like rail 20. At the back'of the typewriter, another comb-like rail 20*, Fig. 1, is provided, in the rear ends of the slots of which the tabulator key levers 5 are also guided on the other side of the fulcrum pin 25.

The stop bar casing is guided at its upper end in a frame 22, Fig. 3, which is preferably placed in'a slot in the back carriage bar 24 with projecting flaps, and is held by screws 23.

The operation of the device is as follows lf the stop bars 4 are to be adjusted relatively to the carrying bars 2 for the tabulator stops then the knob 15. is rotated until the pointer 16 on the indicating scale 17 assumes 'the positions 1. 2, 3 or 4, corresponding to the position desired. after which the tabulator stops? are set to begin the work. When movinL the knob 15 the crank disk 10 is rotated by means of the shaft 14, the bevel wheels 11, 11 and the shaft 10*, and thus by means of the links 9,-the stop bar casing 6 with the stop bar 4 is adjusted. In each position of the crank disk 10 corresponding to thescale, a notch on the circumference of the crank disk isbrou'ght opposite the looking ball 13 with which it engages-and secures the adjusted position of the parts.

In the Figs. 2* to 2, the various positions of the crank disk 10 and the links 9 are illustrated when using four carrying bars 2 for the tabulator stops. It is to be understood that the notches on the crank disk 10 may also be distributed in another manner to that, shown, and further that the distribution must correspond with the number of carrying bars for the tablators are attained.

ulator stops and with the indicating scaie.

ts the stop bars 4 cannot effect an efficient guiding on account of their pivotal arrangement, the tabulator key levers 5 as above stated are guided and secured against tilting, V by means of the comb-like rail 20, while the stopbar casing is positively guided in the frame 22 so that allparts in action when tables orcolumns are being typed are securely guided and possess easy movability,
